LH79524; LH79525

General description

The LH79524/LH79525, powered by an ARM720T, is a complete System-on-Chip with a high level of integration to satisfy a wide range of requirements and applications. The SoC has a fully static design, power management unit, and low voltage operation (1.8 V Core, 3.3 V I/O). With the on-chip voltage regulator, a single 3.3 V supply can be used as well. Robust peripherals and a low-power RISC core provide high performance at a reasonable price.
